Active clinical trials for "Body Weight"

The purpose of this study is to help women lose the weight they gained during their pregnancy using a SmartPhone app the investigators have developed called E-Moms. The investigators hypothesize that the moms given the app to use during the study will lose more weight than the moms who do not use the app.

Primovist-enhanced Magnetic resonance imaging (MRI) and Diffusion Weighted MRI (DW-MRI) is superior to Multidetector Computed axial Tomography (MDCT) in the detection of colorectal liver metastases. Fatty changes in the liver after chemotherapy treatment likely reduces the chances of seeing metastatic lesions on CT especially when the lesions are small (<10 mm). When compared with CT, Primovist-enhanced MRI and DW-MRI have the potential to provide higher contrast resolution enabling better detection of colorectal liver metastases following chemotherapy. Primovist-enhanced MRI and DW-MRI are superior to CT in assessing and predicting treatment response of patients with colorectal liver metastases to chemotherapy. Primovist-enhanced MRI by providing superior resolution may provide improved accuracy in metastatic lesion margin detection thereby providing higher accuracy in estimating tumor response based on size criteria. DW-MRI provides information indirectly about tumor composition and therefore is likely to be superior to MD-CT in assessing treatment response. Two groups of patients will be analyzed. The second group consists of patients with colorectal liver metastases who are to go for chemotherapy prior to surgery for metastases resection. This group will be CT and MRI scanned prior to chemotherapy and after chemotherapy. The first group of patients will consist of those patients who have already received chemotherapy and are likely to have surgery to resect liver metastases. This group will have only one set of scans done 4-6 weeks prior to their operation. The pathology of the resected metastases and CT and MRI images will be analyzed and compared.

This study will help determine the appropriate type, amount and intensity of physical activity most beneficial for preventing weight regain after weight loss in older adults.

Preoperative detection of lymph node metastases in patients with prostate or bladder cancer is crucial for selection of the appropriate treatment strategy (surgery, androgen deprivation with/or without radiation therapy or chemotherapy) and thus for patient prognosis. Until now CT or MRI have been the modalities of choice for preoperative staging procedures. However, current morphological assessment of lymph nodes based on size and shape is unable to detect smaller metastases or liable to give false positive results on lymph nodes with reactive hyperplasia. We hypothesize that USPIO-enhanced MRI combined with DW-MRI will be able to detect pelvic lymph node metastases preoperatively with high sensitivity and specificity.

The prevalence of overweight and obesity is increasing among pregnant women in the United States. More than one-third of women of reproductive age in the US are overweight or obese, and two thirds of women gain more weight in pregnancy than is recommended by the Institute of Medicine guidelines. Maternal obesity during pregnancy increases the risk of complications to both mother and child. Minority women (Blacks and Hispanics) have higher rates of overweight and obesity when they become pregnant, experience higher rates of excessive weight gain during pregnancy, and experience higher rates of maternal and neonatal complications after adjusting for sociodemographic characteristics and comorbidities than Caucasian women. Epidemiologic studies indicate that lifestyle modification programs based on diet and exercise are promising approaches in controlling weight gain as well as in preventing type 2 diabetes in populations at risk. We hypothesize that overweight/obese minority women (Blacks and Hispanics) assigned to a culturally-grounded lifestyle intervention program based on diet and moderate exercise will result in higher compliance with Institute of Medicine guidelines for weight gain than women receiving standard care. Such lifestyle modifications should reduce risk of maternal and neonatal complications. We propose 1) to determine whether a lifestyle intervention program, based on diet and moderate physical activity implemented shortly after first recognition of pregnancy, will result in higher compliance with Institute of Medicine guidelines for weight gain compared to women receiving standard care; 2) to determine the occurrence of carbohydrate intolerance and GDM at 24-28 weeks gestation (after the first 10-12 weeks of intervention) and at 6 weeks postpartum between women in the lifestyle intervention group and women receiving standard care; and 3) to explore the impact of the lifestyle intervention on the development of maternal and fetal complications during pregnancy. By limiting excessive weight gain, the lifestyle intervention program may prevent the burden of obesity-related complications during pregnancy and reduce risk of subsequently developing overt diabetes.

Excessive gestational weight gain is a major public health problem. Traditional face-to-face intervention programs has been shown to be succesful in order to promote healthier weight gains, however, they are time-consuming and expensive. The objectives of this study are to assess whether a 6-month smartphone application can promote healthy gestational weight gain, dietary habits and physical activity in pregnant women.

Many behavioral weight loss interventions have been developed, but still have significant limitations in terms of achieving clinically significant, sustained weight loss. A recent study incorporating Acceptance and Commitment Therapy (ACT) in a randomized clinical trial resulted in participants who attained significantly greater 12-month weight loss in the ACT arm than those assigned to standard behavioral treatment, suggesting that ACT may have the potential to improve behavioral weight loss outcomes. The investigators have developed a novel telephone-delivered version of the ACT behavioral weight loss intervention, based on proven success using ACT telephone counseling intervention for smoking cessation.

Physical inactivity occurs among 65% to 95% of youth with type 1 diabetes (T1D) and based upon limited evidence may contribute to the rapidly growing incidence of overweight among this population. The purpose of the present study is to pilot test a 12-week intensive lifestyle program for adolescents with overweight and T1D utilizing group exercise classes adapted for this population, supplemented with coping skills training and diabetes self-management education to address problem solving behaviors that limit their physical activity and weight control. Our primary aim is to evaluate the changes in physical activity adherence, anthropometrics, and self-management behaviors following this program among sedentary adolescents with T1D and overweight (n=25, OW) compared with sedentary adolescents with T1D and normal weight (n=25, NW). We hypothesize that the OW group will achieve improve physical activity adherence and anthropometrics to the same or greater extent as the NW group and previous Bright Bodies cohorts, and that these changes will correlate with improved exercise-related problem solving. Our secondary aim is to evaluate changes in adipocytokines and epigenetic factors related to the etiology of overweight/obesity following our physical activity intervention. We hypothesize changes in these biomarkers will correlate with changes in anthropometry variables and partially explain any differences in response between the groups and individuals should those occur.

Prospective, double-arm, multi-center cohort study on obese patients, for laparoscopic sleeve gastrectomy versus Roux-en Y gastric bypass

Many patients would benefit from dietary/nutritional support to better manage their conditions but evaluating current intake in relation to personal targets is labour-intensive and often does not feature as part of clinical consultations. Primary objective: test usability and acceptability of 'myfood24 Health' for monitoring dietary intake in a group of patients. Recruit 60 gastroenterology surgery patient (Leeds) and 60 Tier 3 Weight Management patients (30 Leeds/ 30 York). Randomise to 3 groups usual care myfood24Health myfood24Health plus personalised feedback 'diet optimisation engine' which suggests changes to amounts or types of foods During a 2-month follow-up, patients in group 2 or 3 will be asked to record daily diet in myfood24, including weekend and weekdays and use it a minimum of 4 times. HCPs will be able to review diet/nutrients for group 2 and 3 patients and can support dietary change or nutritional goals, as part of patients' ongoing clinical management, during existing scheduled clinic visits (N.B. not all participants will have a scheduled clinic appointment during the study). 2 months after recruitment, all participants will receive a link to an online feedback questionnaire. At end of study, HPCs will be invited to provide feedback during a 30 minute interview.
